Mahlkönig · Flat burrE80S GbW
An 80mm flat-burr commercial espresso grinder with a built-in load cell for real-time grind-by-weight dosing. Now officially a legacy model, replaced by the wireless-enabled E80W GbS, but still floating around at dealers for cafes that want raw speed and weight-based consistency without the cloud connectivity.
The short version
This is a café workhorse: obscene grinding speed, a load cell that actually delivers gram-accurate dosing shot after shot, and burrs built for volume, not fussy single-origin exploration.
Accept that Mahlkönig has already moved on to the Sync-connected E80W, so you are buying yesterday's flagship, and early units shipped with calibration headaches that took real setup time to sort out.
Why people buy it
- Very high grinding speed for peak-hour bars, rated up to 7-8 g/s at 60Hz
- Real grind-by-weight dosing via an integrated load cell, not just a timer guessing at density
Why they don’t
- Discontinued by Mahlkönig and replaced by the E80W GbS, so you are buying a legacy product with uncertain long-term parts support
The full tally
- Very high grinding speed for peak-hour bars, rated up to 7-8 g/s at 60Hz
- Real grind-by-weight dosing via an integrated load cell, not just a timer guessing at density
- Disc Distance Detection lets you track and return to exact grind settings digitally
- Portafilter detection auto-applies the right recipe for up to six baskets
- Discontinued by Mahlkönig and replaced by the E80W GbS, so you are buying a legacy product with uncertain long-term parts support
- Owner reports of factory units arriving badly uncalibrated on both grind adjustment and the internal scale, requiring manual correction
- Big, heavy, loud-adjacent commercial footprint that is overkill and overpriced for anything under real café volume
What the community knows
Years of owner threads, distilled — the community advises against it.
Discontinued, legacy model with documented calibration-from-factory issues; café-grade speed and grind quality when properly dialed, but GbW automation arrives broken and serviceable only through dealer networks. No home-enthusiast rallying point; positioned as stepping-stone…

Worth knowing before you buy — A commercial workhorse discontinued in 2025 — buying used now means orphaned electronics and no factory support path to working GbW accuracy.
Known weak points — Factory calibration failures on load cell and burr distance; portafilter weight scale errors exceeding 2.5% accuracy tolerance; variable dose output (14–18g at 16g target) requiring recalibration post-purchase; wobbly rotary encoder controls despite otherwise solid construction.

Living with it
The part spec sheets skip: counter space, upkeep, and what owners learn later.
The honest note — Owners who want the wireless workflow layer (auto-sync with compatible La Marzocco machines, cloud recipe management) move up to the E80W GbS, which Mahlkönig now positions as the direct successor. Home users who found the E80S oversized or fiddly to calibrate have traded down to single-dose commercial-adjacent grinders like the Ceado or Etzinger Etzmax for a simpler experience.

Feed it right
Week one is dial-in — and stale beans will lose it.
Coffee more than a few weeks past roast won’t extract predictably, and a new grinder gets blamed for it. A balanced burr set: rotate origins freely — it will keep up.

EK43S
The shop-counter version of coffee's most influential bulk grinder: same 98mm flat burrs and 1300W motor as the full EK43, just shorter so it fits under a cabinet. Built for cafes grinding retail bags and pour-over by the pound, and adopted by plenty of home fanatics who don't mind the footprint.
